How to Unlock HTC One Bootloader on Windows 8, 7 & XP

It’s fairly easy to unlock HTC One Bootloader with HTCDev. HTC lets you unlock bootloaders for most of it’s devices, including the flagship HTC One. Unlocking the bootloader opens your device to handful of options for customizing it and installing custom ROMs and custom recoveries on it. There are plenty of custom ROMs available for HTC One that you can install. But before that, you have to unlock the bootloader, root the device and flash custom recovery and then you can flash custom ROMs from recovery mode. So, lets take the first step and unlock the HTC One bootloader. Detailed instructions are provided below:
